Static Calculation of Load of Buried HDPE Pipes with Profiled Wall and Smooth Pipe Inside [PE]

 

# 1985 York

Trials to investigate the deformation and buckling behaviour of HDPE pipes with profiled outer wall and smooth bore are reported. Results show that the deformation and stability check can be carried out in the same way as for solid-wall pipes. However, an additional check on circumferential compressive stresses is required for the relatively thin-walled profile. These compressive stresses must be lower than the permissible buckling stress of the profile and the permissible compressive stress of the material.

The Cyclic Cracked Round Bar (CRB) Test has been applied to study the slow crack growth (SCG) resistance of virgin, recycled, and reprocessed PVC-U. This fracture mechanical test allows a quick ranking of the SCG resistance of PVC-U. A clear correlation between the K-value and the SCG resistance has been elaborated....

Author(s) : Meldt

A method of specifying the HDPE pipes to use in renovation is described. The following factors are considered: flow capacity, stress during insertion into straight and non-straight lines, lifting and buckling forces experienced by the lining while the cavity between it and the old pipe is filled. Four sources of...
